1 Claim.

This invention relates to an article holder in which the relative position of the article in the holder may be varied; and more particularly to an eraser holder in which the eraser is adjustably carried to permit the protruding tip portion efficient use by the operator. An additional object of my invention has been to provide a holder in which the eraser proper is firmly and yet adjustably held in order to provide ready compensation for wear; Still an additional object has been to combine with the eraser a cleaning brush for use on the surface after the erasure has been made.

Other objects of the invention will become apparent from. the specification and from the appended drawing, while the novel features are summarized in the claim.

In said annexed drawing:

Fig. 1 is a side elevation of my improved holder with an eraser mounted therein;

Figs. 2 and 3 are sections through Fig. 1, as indicated by the lines 2--2 and 3-3 thereon;

Fig. i is a fragmentary view of the eraser'end similar to Fig. 2 with the eraser removed; and

Fig. 51s a fragmentary plan view of the brush holder portion. 7

My improved holder consists of two opposed hollow sheet metal halves l held together to provide an er'iclosed housing I! for an eraser l3, its operating mechanism and a brush I5. Each of the halves Hi, as shown in Fig. 2, flare outwardly in .the mid-region. At the ends the halves decrease in thickness, as shown in Fig. 1, to accommodate the eraser and brush, respectively.

The brush receiving portion is of a size and shape to closely receive the shank of the brush and hold the same in place by the inturned erimps If! extending cross-wise of the brush adjacent the holder end. The brush is further held in place by the rivet l8 which, in holding the complementary halves together, also clamps the brush shank.

An eraser receiving opening is provided at the end of the holder opposite the brush and is of such nature as to retain the same in its adjusted position. Thus, the complementary halves ID at the eraser end are resilient and provided with cut-away side portions l9 to permit relative movement of the end lips 2d of the respective halves iii toward each other. The complementary halves normally lie against each other in the position shown in Fig. 4, due to the rivets 22 securing the same together.

The comparatively long eraser l3,,with a rec- 10 tangular cross-section, is slipped between the lips 28 and, dueto the spring in the complementary halves, held by the said lips from falling out of position. The eraser is prevented from moving inwardly by an adjacent abutment, which also I permits compensation for wear at the end.

To adjustably position the eraser a screw 27 with a fiat end 28 to abut the eraser end is provided. The abutment end is of such cross-secvtion as to conform to the inside of the holder and thus be prevented from turning therein. The screw is supported by and traversed back and forth in the holder by the screw wheel 30, which in turn is prevented from lengthwise movement of the complementary recesses 32 in respective halves Hi. Thus as the eraser tip wears, rotation of the threaded member Stipushes a new portion of the eraser from between the lips 29 or, if desired, the abutment 28 may be moved away from the eraser to permit pushing the tip between the 30 lips 20 when not in use. I

The entire holder provides a neat and symmetrical appearance calculated to appeal to the user. Thus the longitudinal ribs 33 adjacent the erasure end smoothly merge with the brush-re- 35 ceiving portion tomaintain an illusion of equal thickness throughout the holder. Uniformity is further obtained by locating the flaring portion of the holder near the middle and reducing the thickness at the ends to receive the eraser and brush or other, article respectively.

It will be seen from the foregoing description that I have provided a novel and improved eraser holder with mechanism to readily compensate for Wear in the tip.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the structure herein disclosed, provided the means stated by the following claim or the equivalent of such stated means be employed. V

I therefore particularly point out and distinctly claim as my invention:

A holder for an eraser and the like comprising a hollow elongated shell of sheet metal having resilient legs of channel section with the flanges of the channels tapered toward the free end of the channel and facing each other to form a substantially rectangular bore, the outer sur- 5 faces of the legs lying in parallel planes when an eraser is between the same, said shell having a flat outwardly flaring portion at its midsection of a thickness substantially the same as the thickness of the legs when an eraser is 10- 10 cated therebetween, said legs being biased toward each other to grip the eraser on its opposed faces, the flanges engaging opposed edges of the eraser JAMES WEBB SAFFOLD.
